WATCI-IMANS TIME-RECORDING CLOCK.

Application filed August 8, 1925. Serial No. 48,927.

The present invention relates to time-1e cording clocks, and moreparticularly to those intended for registering the routine calls ofpatrolmen and watchmen in their rounds of duty and of a character bestadapted for placement in locked and outof-the-way recesses, where theyare fully protected and removed from all danger of being tampered withby those disposed to cover up remissness of duty, while, at the sametime, being readily accessible to regularly constituted authorities forchecking up purposes and dial changing, the patrolman or watchmanregistering his call through the medium of an inserted key, or thetripping of the mechanism through the agency of a pull-cord, eitherbeing readily accomplished from outside the wall, or partition, of thebuilding in which clocks may be located.

The invention has for its principal object the provision of simple andefiicient manually controlled means for recording at regular andpredetermined intervals the scheduled calls of patrolmen and watchmen atdesignated points in their rounds of duty.

A further object is the provision, in a device of this character, of aconstruction permitting installation in locked recesses, or betweenwalls of buildings and adapted for actuation to record patrolmen andwatchmen calls through the agency of pull-cords or a suitable key.

An additional object is the provision of a device of the characterdescribed that is of cheap and durable construction and of certain andpositive operation.

Other objects and advantages will appear as this specificationprogresses, and be more clearly set forth in the claim hereto appended.

In the accompanying drawings forming a part of this specification, andin which similar characters of reference refer to like parts,throughout, I

Figure 1 is a plan section taken through the casing adjacent the dial,as indicated by the line 1-1 of Figure 2, the view being illustrative ofthe form of the casing and arrangement of the movable dial andperforated presser-foot positioned to back the dial while beingperforated by the perforating needle;

Figure 2 is a fragmentary vertical section, showing the interiorlocation of the ings, and in detail my invention comprises, i

in a preferred embodiment, a cylindrical casing 1 having a bottomclosure 2 and a hinged topclosure 3 hinged to the cylindrical casing at4 and provided with a lock 5 adapted to hold the hinged closure inlocked relation with the casing.

The casing 1 is provided with a centrally arranged clock-mechanism 6secured to the bottom closure 2 and provided with the ordinary hour-handarbor 7 to which is attached frictionally a dial stem 8 bearing anannular flange 9 and threaded end 10 adapted to center and support acard-board dial 11. The dial is held in place upon the flange 9 by anannular clamping flange 12 having a knurled knob 13 and tapped toreceive the stem-end 10 into which it is tightly screwed to compress thedial between the flanges.

The dial graduations 14 are arranged to read contraclockwise and runfrom 1 to 12, as indicated in Figure 1, so that, as the dial turns withthe stem 7 in clock-wise movement, the dial graduations are consecutively brought to position at a predetermined point in their travel, asindicated at 15.

The dial is scored concentrically, as indicated at 16, and the hoursub-divisions marked thereon, as shown at 17.

A perforating mechanism 18 is mounted in the casing and comprises acasting 19 having a flanged base 20 adapted to be secured to the bottom2 of the casing by means of rivets, or the like, 21, the said castingbeing provided with a bore 22 extending from the bottom to near theupper end and a counter-bore 23 communicating therewith. The casting 19is provided With a slot 24 formed adjacent its lower end and adapted tohouse a if-shaped member 25, said member being provided With arms 26 and27 and a centrally disposed member 2 having a vertically disposed slot29, the member being free for vertical movementrin the slot 2% of thecasting and for rocking movement upon the pin 30 extending through theslot 29, as hereinafter described,

The member 25 is hole in its normal position, Figures 2 and S, by meansof a follower-pin 31 fitted Within the bore 22 of the casting and havinga tapered lower end 32 adapted to fit and bear in the crotch of themember the followenpin bearing a perforating member 33 which is providedwith punch-point 34% extending through the counter-bore 23 of thecasting.

it coil spring 35 is seated in the upper end of the bore 22 and bearsagainst the upper end of the perforating member 33, the spring urgetending to normally seat the followerpin upon the memb r 25 and hold thepunchpoint retracted immediately adjacentthe dial,- Figures 2 and 3.

A presser-foot 36 is integrally formed with the casing and positioneddirectiy in the path of the punch 34 and provided with a perforation 3'?positioned in the path of the punch and a larger opening 38 positionedadjacent said perforation to provide a sightopening through which thedial graduations may be viewed.

The punch 3d may be actuated by inserting a key 39 through the easinginto the bore 22 until it abuts against the lower end 28 of the member25, whereupon said member is raised upwardly to the position shown inFigure A} and the punch forced through the dial, the dial being heldrigidly in place dur ing this operation by the pressenfoot 36', theparts being returned, upon release of the hey, to normal position,Figure 3.

The clock may be punched at hourly in;

tel-vale, or oftener if desired, and the exact time will be recordedupon the dial for future reference. The dial may be of disk formationand of paper or light card-board, upon which the graduations may beprinted, thus affording a cheap and simple dial adapted for replacementevery twelve hours, should it be required.

Should the clocks be placed in remote recesses or behind partitions, orother inaccessible iocations, cords or light Wire strands 40 and 4 1 maybe attached to the extremities of the arms 26 and 27 for their actuationand lead to any desired place convenient for op eration, the rocking;'of the member 25 in either direction upon its point tending to cause thevertical movement of the followerpin and punch, by virtue of the camlike thrust imparted to the tapered end of the followerpin, the actionserving to produce the necessary perforation.

Having thus described my invention, I claim, and desire to V secure byLetters Patent:

A device of the character described, comprising a perforating mechanismconsisting of an upright cast member having a base and a bore extendingfrom end to end thereof; a transverse slot communlcatmg with id bore andadapted to house a Y-shaped c in member, a slot in said cam member and apin extending through said slot and proviuing a pivot-point and guidefor said Y- shaped member, spring-pressed perforating member mounted insaid bore and normahy resting: in the crotch of said Y-sha-p'ed member,and means for manually rocking said Y-shaped member to force saidperforating member outwardly against the spring urge.

In testin'iony whereof I have hereto affixed my signature.

PETER W KANE.
